Application:
Tris buffer is not
only widely used as a solvent for nucleic acids and proteins, but also has many
important uses. Tris is used for protein crystal growth under different pH
conditions. The low ionic strength characteristics of the Tris buffer can be
used for the formation of intermediate fibers of the nematode (C. elegans)
lamin. Tris is also one of the main components of the protein electrophoresis
buffer. In addition, Tris is an intermediate in the preparation of surfactants,
vulcanization accelerators, and some drugs. Tris is also used as a titration
standard.
